  8. Add Test Users
    • Add at least one test user email (only if you don’t have a Google Organization) — only these accounts will be permitted to run the OAuth flow and index documents.
    • Click Save and Continue, review your settings, then return to the dashboard.
  9. Create OAuth Credentials
    • Go to the Credentials tab and select + Create Credentials → OAuth Client ID

    • Choose Web Application and give it a name like AssistAIConnector.
    • Then configure the following:
      • Authorized JavaScript Origins
      • https://www.tryassist.in/forassist (ASSIST AI Cloud)
    • Authorized Redirect URIs:
      • https://www.tryassist.in/admin/connectors/google-drive/auth/callback
        for ASSIST AI cloud
Click Create, then download the credentials JSON file from the Client Secret panel — you’ll need it in the next step.

​
Indexing

Navigate to the Admin Panel and select the Google Drive connector. Create a new credential and upload the JSON key downloaded in the previous step. Click Authenticate with Google Drive and sign in with the account you’d like to use for indexing. Once complete, select the newly created credential and click Continue to finish configuring the connector.
If you plan on using permission syncing for this connector, the account performing the OAuth flow must have an Admin role in the Google Workspace that has access to the following:
  • Admin console privileges -> Services -> Drive and Docs -> Settings
  • Admin API privileges -> Users -> Read
  • Admin API privileges -> Groups -> Read
  • Admin API privileges -> Organization Units -> Read
This can be set by an admin in the admin panel of the Google Workspace under Account > Admin roles.
